Someone bumped this so I'll bite. I too have a habit of purchasing games, TV shows and movies (all physical) and not touching them for years. Odyssey is still in the shrink-wrap but it's not really 6-years in my case. I mean, I held off on consoles and was going to skip the gen entirely until my wife give it (Switch) as a birthday gift in October of 2022. Pretty late getting the Switch as she had one and I always thought, I'd just play hers. I bought the popular titles but Odyssey ironically to OPs thread, is one in my back catalog. Played every mainline Mario game with the exception of purchasing and never playing Galaxy 1 or 2 (this was due to my gripe with the Wii and it's insidious shovel ware). I'm playing two games at the time but I plan to get to Odyssey sometime this Spring.
If anyone can confirm that this is the unofficial successor to Super Mario 64, that'd be sweet.
